E. waves, or GLEN CAN-OPENER..

Statejof New York, havefinvented certain new and useful Improvements in Can-Openers, 'o f which the followlng is a specification,

such as will enable those skilled in the art to which it.appertains to make and use the same.

l hisjinvention relates to devices for open ing cansand the object thereof is to provide. an improved-device of this .class designedi particularly to open cans containingliquid;

' ';the blade 6 is cut from the material of the densed milk,- soups and liquid products of.

substances, such as, sterilized milk, conany kind or class, a further object being to provide'a can'opener ofthe class a'nd for the purpose specified, whichfis simple 1n construction and comparatively inexpensive,

and which may be easily manipulated; and withtheseand'otherobjects inview the invention consists in a device of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the fol.-

lowing specif cation 'of which the accompanying; drawing forms a part, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which Figure l is aside view of a can the top portion of which is shown in section, and showing also one form of my improved can opener, and'one stepvin the operation thereof-; -Fig. 2 a view similar to Fig. 1 and showing another step in the operation of the can opener Fig. 3 a plan view of the can i and showing the result produced by the first step in the operation of the opener ;-Fig. .4 az'view similar to Fig. 3 but showing the result-{produced by the second step in the operation of the opener and Fig. 5a bottom plan- View of the opener.

In the accomp'anylng drawing I v have shown at a a can of the class usually em- #in the practice of my invention, I provide a- '50 ployed as containers for various ln'nds and cl'asses'offfood products in liquid form, and

came ener comprising an oblong body part b which may be slightly wider at one end than at the other, and the end portion b of which forms a handle for the manipulation of the device.

5 freeway or handle 22 is provided-opposite *the end portion 6 thereof with a blade 0 which projects therefrom at right angles theret0,"and said blade comprises a penetrating point and forwardly curved side portions having cutting edges which-taper from the point toward, .and gradually increase'in width, to the body or handle; and the for lwardly directed curve of theside portions bf the blade is sucli a'sito make said blade approiiimately semi-circul'arin cross section -at itswidest point, and the backtliereof is straight or approximately soin longitudinal "section. Inthe form of constructionshown shown at'c, but this-curve of the side edges 0 of theblade is not an absolutely essential feature, and it will'be understood that the side edges 0 are cutting edges and the point- 0 islso formed as to be easily forced through the head ar, of the can when the opener is placed horizontally thereover. The-handle end portion of-th'e body of the opener is preferably provided, at a predeterminerf distance from the blade 0 with a prong d the .object of which is to produce a vent opening 6 in the head of the can when the opener is manipulated as hereinafter described, and in the handle end portion b of the body part of the device is preferably formed an apertureb whereby the device may be suspended from .a hook or other support when not in use.

In the operation of this form of my improved can-opener the said implement is placed on the top; or head of the can, in the position shown in Fig. '1', with the point 0 of the blade resting on said head ofthe can adjacent to one rim thereof and the body or handleportion of the opener extending diametrically acfoss said head. With one hand used in supportingthe opener in this position the other hand is used for fore ing the blade 0- and prong d downwardly, I through the head of the can, as clearly shown 10 5 'in Fig.- l after which, while the end b of the body part ofthe' device is held firmly 'i na the position shownin Fig. 1, the other end portion thereof is raised and swung backwardly in a plane passing centrally and vertically through the can; The result of the first step of this 0 ration .is shown in Fig. 3, and the result ol the second step is shown in Fig. 4, and from these figures it will be lar or an approximately semi-circular aperture a, the tongue portion a being bent backwardly under the head a of the can by the pointed end portion of the blade 0 when the handle portion of the opener is moved backwardly as described. With the aperture a in the-head of the can and the vent e to permit air to enter the can. the contents thereof maybe freely discharged through said aperture, as will be readily understood, and my invention is not limited to theuse of the pron (Z, the vent being only to facilitate the discharge of the contents of the can, which operation might also be facilitated by enlarging the aperture a or changin the form'thereof.

Having lly described my invention what I claim as new and desire to secure by Letters Patent is A can opener comprislng a main body or handle portion provided at one side andadj acent to one end with a blade which projects at right angles thereto, said blade belng of crescent form in cross section and the side edges thereof being convergent to a central point, said blade being widest at the handle or body portion, and said handle or body portion being provided .back of the blade with -a projecting member which forms a stop to limit the distance the blade can be forced into a can, and which also forms a fulcrum on which the body or handle por- JAMES M, PURDY.
